50+ knot direct crosswind landings (better line up with the upwind lights...and looking out the other guys window)
10,000 feet at the marker.....good luck.
Give someone a pitot blockage on one side in any glass cockpit followed by a climb or descent..... they will THINK they are either gonna stall or overspeed and have very little idea wtf is going on.
Full stall at high altitude in a swept wing..... fun stuff.
TCAS descend near a mountain...... "Descend, Descend....... WHOOP, WHOOP PULL UP!"
Any very strong windshear/microburst on TO or landing. Landing you may do a touch/go if you do it right...... Do the TO one and watch how far they roll before they realize they will never make Vr.
